Loss-in-Weight Feeder
HWS loss-in-weight feeders, also called loss-in-weight batching scales, are high-precision continuous dosing equipment.
Built on dynamic loss-in-weight weighing technology, the system tracks real-time material weight changes inside weighing hoppers and adjusts feed rate via closed-loop control.
It delivers continuous stable dosing while refilling materials intermittently.
Three standard models cover all material types: HWS-Y liquid feeder, HWS-F twin screw powder feeder, HWS-Z vibratory granular feeder.
They fit low-flow, high-precision multi-formula automatic batching for lithium battery, food, chemical, construction, feed and plastic manufacturers.
As core dosing equipment for automated batching systems, they stabilize mixing accuracy and improve production consistency for global smart factories.
Modular Machine Construction
All units adopt modular SUS304 stainless steel or manganese steel frames, split into three independent functional modules for easy disassembly, cleaning and maintenance.
- High Precision Weighing Assembly
Equipped with high-sensitivity load cells and fully sealed dust-proof weighing hoppers.
They block dust and moisture interference to capture tiny weight fluctuations and maintain stable metering performance.
- Custom Dosing Mechanism
Special feeding structures matched to different material features
Twin screw feeder: for sticky fine powders
HWS-F Twin Screw Weightlessness Scale
Vibratory feeder: for free-flowing granules
HWS-Z Vibration Weightlessness Scale
Pump unit: for liquid raw materials
HWS-Y Liquid Weightlessness Scale
Adjustable feed speed prevents material bridging, arching and uneven output.
- Intelligent Touchscreen Control System
Touch HMI comes with auto refilling, self-calibration and formula storage functions.
Real-time weight data can be exported to connect with factory MES and ERP smoothly.
Optional IoT module supports remote parameter editing, real-time operation monitoring and full production batch traceability.
Core Product Advantages
- Ultra Precise Dosing
Proprietary dynamic weight loss compensation algorithm offsets errors caused by equipment vibration and material drop impact.
Dosing accuracy ranges from ±0.1% to ±0.5%, ensuring consistent ingredient ratios across all production formulas.
- Fully Automated Unattended Operation
The machine automatically finishes refilling, weighing and dosing without manual work.
It stores over 100 production formulas for one-click switching and supports 24/7 non-stop production.
Optional Ethernet or 5G communication enables remote management, suitable for Industry 4.0 factory digital upgrading.
- High Throughput & Stable Output
Dosing keeps running continuously during hopper refilling without flow fluctuation, matching the cycle of high-speed production lines.
It eliminates human weighing errors and raw material waste to lift overall production efficiency.
- Versatile for Harsh Working Conditions
Three model lines handle liquid, powder and granular materials.
Waterproof and dustproof stainless steel housing adapts to complex factory conditions.
Modular structure enables quick full cleaning, meeting strict hygiene standards for food and pharmaceutical processing.
